Part 3: Hazard Overview

Hazard Category:

Invasion Route:

Health Hazards: Irritating to eyes, skin, mucous membranes, and upper respiratory tract.
. At present, there have been no reports of occupational injuries in industrial use.

Environmental hazards: Harmful to the environment, can cause pollution to water bodies and the atmosphere.

Explosive hazard: This product is flammable and irritating.

Part 4: First aid measures

Skin contact: Remove contaminated clothing and rinse with plenty of flowing water.
. Seek medical attention.

Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention.

Inhalation: Remove from the scene to a place with fresh air. If breathing is difficult, administer oxygen. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

Part 5: Fire Protection Measures

Hazardous characteristics: Powder and air can form explosive mixtures, and when they reach a certain concentration, they will explode upon contact with sparks.
. Affected by high thermal decomposition, it releases irritating smoke.

Harmful combustion products: carbon monoxide, carbon dioxide.

Fire extinguishing method: Firefighters must wear gas masks and full body firefighting suits, and extinguish the fire in the upwind direction. Fire extinguishing agents: misty water, foam, dry powder, carbon dioxide, sand.

Part 6: Emergency Response to Leakage

Emergency Response: Isolate the leakage contaminated area and restrict access.
. Cut off the fire source. It is recommended that emergency personnel wear dust masks (full face shields) and gas protective clothing. Avoid dust, sweep up carefully, place in a bag and transfer to a safe place. If there is a large leakage, cover it with plastic cloth or canvas. Collect, recycle or transport to waste disposal sites for disposal.

Part 7: Handling and Storage Precautions: Closed operation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti toxic work clothes, and rubber gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidants, reducing agents, and alkalis. Handle with care during transportation to prevent damage to packaging and containers. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances. Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. It should be stored separately from oxidants, reducing agents, and alkalis, and avoid mixing storage. Equip with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaked materials. Part 8: Contact Control/Personal Protection China MAC (mg/m3): No Standards Developed Former Soviet Union MAC (mg/m3): No Standards Developed TLVTN: No Standards Developed TLVWN: No Standards Developed Monitoring Methods: Engineering Control: Closed Operations. Respiratory protection: When the dust concentration in the air exceeds the standard, a self-priming filter dust mask must be worn. During emergency rescue or evacuation, air respirators should be worn. Eye protection: Wear chemical safety goggles. Body protection: Wear work clothes that prevent toxic substances from penetrating. Hand protection: Wear rubber gloves. Other protections: Smoking is strictly prohibited at the work site. Pay attention to personal hygiene and cleanliness. Part 9: Physical and Chemical Characteristics Appearance and Characteristics: White solid powder, capable of sublimation. PH: Melting point (℃): 153 Relative density (water=1): 1.36 Boiling point (℃): 330.5 (decomposition) Relative vapor density (air=1): No data available Molecular formula: C6H10O4 Molecular weight: 146.14 Main components: Content: ≥ 99.8%; Iron ≤ 1.0ppm; Nitric acid ≤ 10.0ppm. Saturated vapor pressure (kPa): 1.33 (165 ℃) Combustion heat (kJ/mol): No data critical temperature (℃): No data critical pressure (MPa): No data logarithmic value of octanol/water partition coefficient: No data flash point (℃): No data upper explosive limit% (V/V): No data ignition temperature (℃): No data lower explosive limit% (V/V): No data solubility: Slightly soluble in water, slightly soluble in ether, soluble in ethanol. Main application: Used in nylon production, as well as in the production of lubricants and adhesives. Other physical and chemical properties: Part 10: Stability and reactivity Stability: Prohibited compounds: Alkali, oxidant, reducing agent. Conditions for avoiding contact: Aggregation hazard: Decomposition products: Part 11: Toxicological data Acute toxicity: LD50: 1900 mg/kg (oral administration to mice); 280 mg/kg (subcutaneously in mice)

LC50: No data available. Subacute and chronic toxicity: Irritation: Allergenicity: Mutability: Teratoxicity: Carcinogenicity: Part 12: Ecological data. Ecotoxicity: Biodegradability: Non biodegradability: Bioaccumulation or bioaccumulation: Other harmful effects: This substance is harmful to the environment and can cause pollution to water bodies and the atmosphere. Organic acids can easily form acid rain in atmospheric chemistry and physical changes. Therefore, when the pH value drops below 5, it will cause serious harm to animals and plants, and the reproduction and development of fish will be severely affected. Metals in the soil and sediment of the watershed can be dissolved and enter the water, poisoning fish. Water acidification can also cause changes in the composition and structure of aquatic organisms, with an increase in acid resistant algae and fungi, a decrease in rooted plants, bacteria, and vertebrates, and a decrease in the decomposition rate of organic matter. After acidification, it can seriously lead to a decrease or death of fish in lakes and rivers. Part 13: Waste Disposal Nature of Waste: Waste Disposal Methods: Before disposal, relevant national and local regulations should be consulted. Suggest using incineration method for disposal. Disposal precautions: Part 14: Transport information Dangerous goods number: No data UN number: No data Packaging mark: Packaging category: Z01 Packaging method: No data. Transportation precautions: The packaging should be intact and the loading should be secure during shipment. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport with oxidants, reducing agents, alkalis, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures. The vehicle should be thoroughly cleaned after transportation. Part 15: Regulations and Information Regulations and Information Regulations on the Safety Management of Hazardous Chemicals (issued by the State Council on February 17, 1987), Implementation Rules for the Regulations on the Safety Management of Hazardous Chemicals (Hua Lao Fa [1992] No. 677), Regulations on the Safe Use of Chemicals in the Workplace ([1996] Ministry of Labor Fa No. 423) and other regulations have made corresponding provisions for the safe use, production, storage, transportation, loading and unloading of hazardous chemicals.
